Vacuum Air Circuit Breakers in MV Distribution System for Electrical Construction
The air vacuum circuit breakers are of the triple pole indoor type for rated voltage 24 KV. They operate on the vacuum arc quenching principle and outstandingly cost effective. The vacuum breaker consists of the mechanism 2 housing complete with stored energy mechanism and control elements. The three poles with vacuum interrupters, cast resin insulators and bracing struts, and the operating rods connecting the mechanism with the breaker poles.
